syphilis, the date of death would probably be within the past 50 

 years. The second skull was from Meningie. It was of the 

 dolichocephalic type, with the frontal angle very low, the orbital 

 ridges very thick and prominent, and the calvarium had attained 

 the thickness of fully an inch in places. The skull was presented 

 to the museum by the exhibitor. A. W. Fletcher, B.Sc, ex- 

 hibited Cambrian fossils from Ardrossan and Curramulka, Yorke 

 Peninsula. From Ardrossan there were of the trilobita the genus 

 Dolicliometojnis ; and of the order pteropoda the genera Hyolithes 

 and Stenotheca. From Curramulka various trilobitpe, and an in- 

 vaginated Hyolithes. Calcite, gypsum, fluorspar, copper- and 

 iron-pyrites were found as accessory minerals with the limestone. 

 Prof. Tate spoke of the interest attached to the specimens, and 

 stated that the finding of the fossiliferous limestone at Curra- 

 mulka rendered it probable that there w^as a bar of Archsean rock 

 extending across Yorke Peninsula from Ardrossan to Port Vic- 

 toria. The invaginated pteropod, Salterella or Hyolithes, was 

 strictly Cambrian in its range, and with its associates fixed very 

 definitely the geological horizon of the specimens. The Cambrian 

 limestones of the Flinders Range exhibit relationship with the 

 Ardrossan section in its corals, and the Curramulka section in 

 its trilobites. 



J. J. East exhibited a specimen of asbestos obtained by J. L. 

 Johnson from Nackera, and a number of mineralogical specimens 

 from Mount Crawford. 



J. G. O. Tepper, F.L.S., exhibited cocoons and moths of the 

 family Arctiidse, sent from Mount Gambier by W. Weld, Avho 

 observed them feeding on Acacia longifolia ; also the cocoons of 

 Cossus cinereus, and a specimen of ichneumon which is parasitic 

 on it. The cocoon had an ovipositor inserted into it, and con- 

 tained about 50 of the parasites. Also a collection of 80 species 

 of Australian lichens which had been identified by the Rev. F. R. 

 M. Wilson, of Victoria. 



Ordinary Meeting, August 5^ 1890. 



Dr. Stirling in the chair. 



Exhibits. — A. Zietz exhibited a specimen of Glareola grallaria, 

 a bird new for South Australia, about the size of an English 

 starling, whose general habitat is Central Austalia. In 1884 it 

 was for a few months very numerous about Goodwood, and then 

 disappeared altogether. Also a species of petrel, Piiffinus 

 carnipes, picked up on the Glenelg beach in 1888. According to 

 Dr. Ramsay's list it is only found on the western and south- 

 western coasts. Also a specimen of musk-duck, Biziura lohata, 

 from Cooper's Creek, forw^arded by AV. Lamb ; it was much larger
